CSV: RowNumber and line breaks inside fields

[shameleo]

RFC4180 allows line break inside quoted field, and Sylvan.Data.Csv handles this just fine, but CsvDataReader.RowNumber counts records, not actually read lines of file. Could you add one more property for actually read lines? Its important in case of some validation error, when we need to reference to the file line. I guess it shouldn't affect performance in any noticable way?

This sounds like a reasonable feature. If you want to implement it, I'd probably merge it.
